Hey Fernando, did you ever wire this up? If so, what did you wind up doing?

I don't remember seeing one last year either. I don't know who put together those press releases, but Gordon Moore retired as president in September 2023 so maybe that is related?

Hi sorry if this is a silly question but my G4s are in the band for 606-648 MHz I'm just wondering will this be okay for Leipzig Germany? Thank you

I’d like to see a detail pic of how you attached the axle. Did you install a bracket or pillow block or something?

Superb. I'm doing less 'larger' productions (maybe we all are, unfortunately) so I sold my BS Mag Jr and have been looking for an alternative. The Olympia was on the top of the list but this certainly pushes me to pull the trigger. Thanks a ton for sharing the parts list!

Everyday feels like Aprils fools day... sorry to not see Lectro add some comedy to my day.. OR i missed it..

A great idea for a small cart! Seems like you must push it from the small wheels end? I'll definitely take a closer look at your parts list. Question... what bag is your MixPre6 in and does it come with that kickstand or is the kickstand something else? Thanks!

Wow very nice!

Finished this build in March of '23. I've posted in other groups on FB, but wanted to make it available here. I appreciated seeing lots of other routes that others took before I decided on my build. Links to all parts below. Took a lot of trial and error with parts, fasteners, finding the right tools, but finally got her finished for a good while. Posting this with the hopes that it'll save others literal days of shopping, planning, shipping parts back, and throwing things away. Upgraded to 5" casters in the front because I work in rough terrain sometimes, and I based the rear wheels on that, so she's level, and she still folds!

The title says it all.

Just buy the original Inspired energy. They are cheap and have never failed me since I found them " with VIN's help" maybe 10 years ago. Check AudioDept or Gotham sound have good prices.

That’s what I thought too at first but then I looked into what Auracast is and how it’s different from the usual Bluetooth tech. Is more like a traditional radio broadcast and doesn’t require the same bidirectional pairing that Bluetooth does. This also allows it to use a lot more transmission power. Worth a look for certain setups. We regularly get asked by people (producers, executives, etc..) if they can use their wireless headphones or earbuds to listen in and as time goes on this is only going to become a more common request and eventually will get embarrassing to keep turning them down. I also have no interest in troubleshooting individual phones but if it’s something people can just figure out on their own like getting on a public WiFi and proves reliable then it has potential. And counterpoint, Comteks are not completely trouble-free either. Good point about the revenue stream with Comteks but you could charge for the Auracast transmitter especially if you can make the case it’s being requested by above the line folks.

How about this brand? I tried to disassemble it, and it contained Panasonic batteries. It is prefect to use.

No thanks. Bluetooth is not reliable on set, has a delay, and would you really save time/workload handling out Comteks vs teaching people how to set things up on their phones? And then blame you when something goes wrong. Imagine trying to mix while you’re circled by people wanting you to troubleshoot…. Besides, Comtek / IFB rental income is not something any of us should want to give up. And it still works better than anything else available.

If this is your highest priority, going by brand or format probably isn't the best approach. It's very difficult to assess that kind of risk accurately on the basis of brand, especially since the underlying cells tend to be sourced elsewhere anyway. Even the with the worst brands, total meltdown is a rare, black-swan event, so there isn't really a good way of getting real data as a consumer. Only the manufacturer or maybe the FCC would have enough data to make that judgement, and even then I would have my doubts. I would start with: Chemistry. As you are aware, pretty much all lithium batteries have a risk of runaway heating if the battery gets above a certain internal temperature. It's a gradual process, and there are different stages of runaway, but the risk starts around 80°C (ballpark, and apparently quite battery-specific). The only sure way to eliminate that particular risk is to use a different chemistry. This will mean a serious trade-off in capacity and weight, but non-lithium batteries generally do not have a thermal runaway point that is inherent to the chemistry. Other chemistries are still explosive and flammable, and the non-cell components can still fail catastrophically, but the peculiar idiosyncrasy of lithium to overheat and catch fire can be avoided. You *might* still find NiCd batteries in IDX / NP1 format if you look carefully, otherwise a lead-acid chemistry may be the easiest to get hold of. I would try and find a NiMH chemistry if you can, but I've only seen this chemistry used in AA format, not larger, higher voltage battery packs. Assuming you are willing to risk lithium chemistry in the first place, and you are just trying to minimize risk, the obvious precaution is to make sure if something short-circuits in your recorder, the battery is behind a fuse so it will never see an open circuit. This basically means using a BDS system with an appropriate fuse. Next, heat is proportionate to current, and current and voltage are inversely related. If you have more voltage available, your recorder will draw less current to receive the same amount of power (wattage). So, use a battery that is near the maximum input voltage your recorder can accept (16V for the F8n if I recall correctly). In practice, the eSmart batteries (& IDX NP batteries) are nominally 14.7V, which is probably as close as you will get. Also in practice, your recorder draws so little power that heating due to current is pretty minimal, but it is something to think about if you start piling up additional equipment in your bag. External sources of heat are probably more realistic threats from a safety perspective. So, don't leave the battery in direct sunlight (or a hot car), and don't keep the battery directly next to a source of heat (i.e. your recorder). Find a way to ensure that the battery is vented so that heat that the battery creates internally while in use has somewhere to go (i.e., don't bury it in your bag and surround it with foam). If the climate you live in is exceptionally hot, that increases the risk overall Mainly, it reduces the headroom for additional heating before thermal runaway begins, so the battery can supply less power safely. See the previous paragraph: The amount of power your recorder draws on its own (and therefore the amount of heat it creates in the battery) is probably pretty low, therefore, even in a hot climate you are probably ok. Lastly, mechanical failure can create internal shorts in the battery. This is one place where brand / format / design *can* be assessed a bit more reliably. You want a battery that is physically robust. I'd say the eSmart and IDX NP batteries are both pretty good in this regard; I'd give the edge to IDX, but both are tougher than your average camera battery, and much better than some of the generic USB "power packs" that you see on Amazon. All things considered, the eSmart / IDX formats that are commonly in use are both pretty good choices compared to a more DIY approach: They are physically robust, have a voltage output that will keep current and temperature low, and they can be remoted away from the recorder as heat source via a BDS cable. Make sure your BDS is adequately fused, and you've covered most of your bases. There's probably people more paranoid than me that can think of some other modes failure to think about, but I think I've covered the big ones.

Hi John! I've been looking for this kind of clip since I bought my PS 605, but it seems they no longer sell them or are discontinued. Do you still have the file to print them so I could so I can make the most out of my harness?

I have the Accsoon CineEyes Pro. It works really well and works at a greater distances than my friend's Teradek Bolt. When I am shooting House Hunters, the producer is able to see my video feed on the second floor when I am in the basement. The other DP has a Teredek and more often than not, the producer has to be on the same floor as him in order to get a reliable signal. But, the Accsoon sometimes interferes with some Bolt receivers. I don't have a field spectrum analyser capable of scanning 2.4 or 5 so I can't tell what is what scientifically. I can recommend Accsoon. I have had my unit for 5 years. When the transmitter display backlight stopped working they replaced the hole display free of charge. Outside of warranty.

As external DC power supplies, I run my F8 on either an 'Alphasun' 26,800mAh/99Wh slimline external powerbank - I think I bought it on a crowdfunding website - which just goes on and on (its display shows its internal temperature as well as DC voltage, and whether its AC output is switched on or off), or I use an 'omnicharge' 'Omni Ultimate' (ditto pretty much everything above) with a 38,400mAh 142Wh output. It's a bit bigger, and about twice as heavy as the 'Alphasun'. Apparently, although 38,400mAh, it's acceptable on planes as it's TSA Approved. The 'Alphasun' has three outputs (1 slow USB-A, 1 fast USB-A and one USB-C), and you can choose pretty much whatever voltage you want to get out of them, from 3.6v to 21v at up to 3.5amps. The 'omnicharge' offers 5v to 20v at up to 3amps. Either will run my F8 for days. The 'Alphasun' also has an integral 5v 1amp wireless charging pad ..for phones, for example. The 'Alphasun' came with its own mains-to 19v output plug-in-the-wall charger. The 'omnicharge' can be charged with any DC source of 5v to 32v with a circular coaxial plug on it. I can't find the 'Alphasun' online anywhere, but 'omnicharge' seems to be still going strong at https://uk.omnicharge.co/collections/omnicharge-power-banks The US store is at https://www.omnicharge.co/collections/omnicharge-power-banks The 'omni ultimate+' is shown as £399.00 - or $399.00 in the US store - and appears to come with a 45w wall-plug charger. I can recommend either, or both, of them. I haven't used any other 'powerbank' DC sources with my F8.

I used many solutions, from NP1 to sony LP,USB powerbanks, V lock, 18650, even motorcycle batteries (sometimes you gotta find a solution...). with more or less safety. being able to read the temperature in your battery makes it very useful to avoid the kind of problems mentioned IMHO. As for safety circuits, im not sure but Antoine Malnati from Audioroot or @Andrew From Deity could surely answer this. I use esmart batteries since audioroot 1st gen and would never change to any other system now. I flewn all over the world with it and the weight/space/effiency ratio is unbeatable, would love seeing a 50wH semi battery from deity tho... as for powering a bigger workflow cart based, i'm eying the AC powerstations such as ecoflow

I second IDX lithium batteries. They’re very high quality, have many safety features built in and have never let me down. Not a smart battery but just change it out before the voltage dives too low and you’ll be smart enough.

I'll counter that by adding that I have been using IDX batteries exclusively since...well...as far as i can remember in my sound mixing career - let's say decades. I haven't used anything else. Obviously my BDS has changed from basic spliced cables and multipliers, to newer BDS designed for "smart" batteries but only using them for capacity telemetry and not the bells and whistles it offers. I've never had an IDX NP style battery fail me, ever. Sure, some have lost their charge but that is an expected outcome to constant use. I have had issues with V-mounts, but most here don't use that especially if you air travel. Take that with a grain of salt. Smart batteries are great, I see how they have a place in our workflow.
